Java IQ.getStanzaId方法代碼示例

import org.jivesoftware.smack.packet.IQ; //導入方法依賴的package包/類
/**
 * Filters for packets which are a valid reply to an IQ request.
 * <p>
 * Such a stanza(/packet) must have the same stanza(/packet) id and must be an IQ stanza(/packet) of type
 * <code>RESULT</code> or <code>ERROR</code>. Moreover, it is necessary to check
 * the <code>from</code> address to ignore forged replies.
 * <p>
 * We accept a <code>from</code> address if one of the following is true:
 * <ul>
 * <li>It matches the <code>to</code> address of the request.
 * <li>The <code>to</code> address of the request was empty and the
 * <code>from</code> address matches either the bare jid of the server or the
 * (bare or full jid) of the client.
 * <li>To <code>to</code> was our bare address and the <code>from</code> is empty.
 * </ul>
 * <p>
 * For a discussion of the issues, see the thread "Spoofing of iq ids and
 * misbehaving servers" from 2014-01 on the [email protected] mailing list
 * and following discussion in February and March.
 *
 * @param iqPacket An IQ request. Filter for replies to this packet.
